Specification of Letters Patent.

Application filed March 14, 1912. SerialNo. 683,823.

specification, and to the reference-numerals marked thereon. I

My present invention relates to improvements in mangles or ironing machines, particularly of the type adapted for ironing what is known as flat work, such as ,towels,

' handkerchiefs, sheets and the like, and embodying a series of rolls rota-ting against suitably shaped steam chests for ironing the goods on one side and an apron moving in engagement with a rotating drum for ironing the goods on the opposite side, and it has for a principal object to provide an improved mechanism for actuating the roll supports, to move the rolls bodily away from their cooperating surfaces.

Another object of my invention resides in the provision of means for indicating to the operator the distance through which the rolls move, when being lowered, so as to maintain a perfect control; over thepressure exerted on the work.

Still another object of my improvement is the provision of certain novel features of construction whereby access may readily be had to the machine at the point where the work is carried from the drum to the top of the apron, and the operating parts may bev easily moved out of their operative -po sitions.

To these and other ends the invention consists in certain improvements and combinations of parts all as will be hereinafter more fully described, the novel features being pointed out in the claims at the end of the.

specification.

Similar reference numerals throughout the several figures indicate the sameparts. In the present embodiment, the invention .is shown in connection with a known type of mangle or ironing machine, which embodies a main section 1 and a supplemental Patented Mar. 14:, 1 916. d

section 2 secured to the main section in any approved manner, it being understood that there may be two or more of such supplemental sections arranged together, and my invention is applicable to a single section or to a plurality of sections by merely modifying the present arrangement to accommodate the particular needs of the machine.

The section 1 includes the drum 3,. ironing rolls .4, 5 and 6, and the apron guiding roll 7, arranged adjacent to the drum, as shown in Fig. 2. The section 2 comprises steam chests 9 whlch are provided with concaved upper surfaces arranged to receive the rolls --10, the latter being mounted on movable supports, which in the present instance, comprise yokes 11 carried by the pivotally I mounted arms 12 and adapted to be moved vertically in a manner that will hereinafter be set forth. I

The parts of the machine are operated nicates -movement toto thedriven member by means of a suitable clutch, comprising clutch elements 17 and 18 respectively, the latter being slidable on the driving shaft and operable by means of a shifter 19 which is pivoted at 20 and adapted to be actuated in a manner that I w ill'now describe. Fixed on the shaft 13 is a pinion 21 which is constantly in engagement with the gear wheel 22, the latter being loosely mounted on the shaft 23 which is normally stationary, and adapted to r0- tate in a manner that will appear presently. The shifter 19 is arranged to be actuated automatically, to stop movement of the rolls in case the operators hand gets caught, or moves too far toward the feeding point of the machine, and is actuated by means of the cam disk 24 fixed on the outer end of the shaft 23, the latter being provided with a plate 26, said plate carrying the springcontrolled pivotally mounted locking abutment 27 which is arranged to engage one of the projections 28 on the gear wheel 22, whereby the plate 26 and the cam disk 24 are rotated with the gear wheel, and the shifter is operated. The locking abutment 27 is provided with a tail piece 29, movable between the pins 30 and actuated by the spring 31. The-locking abutment is held vin normal or unlocking position by means of the lever .32 which' is connected to the finger board 33 through the connecting rod 34, as usual in automatically controlled stop mechanisms of this type.

It is the purpose 9f my-invention to pro vide for raising and lowering the rolls of the machine, by power actuated means, and from the driving shaft 13, either simultaneously with the movement of the other parts of the machine, or independently thereof, that is to say, when the machine is not in operation, and to this end, I arrange the shaft 35 so as to be actuated from thegear wheel 22 in .a manner that will presently be described, said shaft 35 serving to control the movement of the roll supports. Arranged on the shaft '35 are eccentrics 36 which are operatively connected to the rock arms 37, of angle levers which are in turn connected to the rolls 10 by means of the connecting rods 38, and to therolls 5' and 6 by means of levers 39 and connecting rods 40. The rolls 5 and 6 are mounted on supports 41, pivoted at 42, as shown in Fig. 2. It will be seen that when the shaft 35 is rotated, the several roll supports are simulengages scribed with projections 43 which are adapt.

ed toengage and rotate the plate 44, the latter being keyed to the shaft 23 and having connected thereto a pinion 45 in engagement with a gear 46 which rotates in suitable bearings and carries .a pinion 47 arranged to engage the gear wheel 48, the latter being keyed to the shaft 35. The plate 44 carries a locking abutment 49 which is pivotally mounted and provided with a tail piece 50 movable between pins 51 .and controlled by a spring 52. The looking abutment 49 engages one or the other of the projections 43 on the gear wheel .22 when the tail piece 50 is released, the being held in normal position, as shown in Fig. 7, by means of a lever 53 which is arranged to be actuated by the treadle 54 through the crank arm 55 and connecting rod 56. The extent of movement of the shaft 35, and consequent movement of the roll supports, is controlled by a notched disk 57 which is keyed on the shaft 35 and the arm 58 carried by the lever 53 so that upon actuating the treadle 54, the shaft 35 will be rotated through the mechanism already described until the arm 58 drops into of the disk 57. By providing three ad]acent notches, .as in the present embodiment, I am able to obtain a maximum, minimum, and intermediate degree of pressure of the rolls, as desired. When the roll supports are being lowered, the weight may be sufficient to cause a faster movement than that band-brake 61,

which is fixed 8 5: latter I driving mechanism. It is also desirable to provide means for enabling the operator of the machine to. determine accurately the position of the roll supports and the amount of pressure exerted when they are lowered, and to this end, in the present embodiment, I provide a stationary indicating plate 63 having suitable graduations marked thereon. Goiiperating with said indicating plate is a hand or indicator 64 which is pivotally permits a yielding downward movement and overcomes any'lost motion between the pa s- The particular form and arrangement of the indicating mechanism that I have just described is not essential .to' the object of my invention, and is merely one embodiment, illustrating the manner in which the result may be obtained.

. The apron 8 is guided around suitable .rolls', as shown in Fig. 2, and as usual in this type of machine. The upper part of the apron travels around the roll 7,. already mentioned, and cooperating with said r0117 are smaller rolls 69 and 70 which serve to guide the belts 71 that direct the work around the roll 7 to the upper surface of the apron 8 from which it is taken off bythe operators. It is sometimes desirable to obtain access to the exterior of the drum at the point wherethe roll 7 engages, and to this end, I mount said roll 7 and also roll 69 on movable supports, with means for holding them normally in operative position. In the present embodiment, the roll 7 is mounted on the support 72 pivoted at 73 whereby the roll may be swung back to the position shown in Fig. 14, while the roll 69' is mounted on the-support74 pivoted at 75. In order to hold the rolls in operative position, I provide means for locking the supports together, such means preferably consisting of a latch 76 pivoted to the support 72 and arranged to cooperate with a projection 77 on the support 74, and to hold the parts normally in cooperative engagement, as shown in Fig. 13. The roll 70 is held in inoperative position, as'shown in Fig. 14, by means of a locking member 78 which carries'the projection 79 for engagement with the recess 80. The roll 70 is mounted in bearings fixedly supported on the rock shaft 81, which may be actuated by means of the hand lever 82, similar levers 88 and 84 being arranged to control the positionof the rolls 69 and 7. Also supported on the'shaft 81 are the doffer-bars 85, which are preferably arranged as shown in Fig. 11. It is necessary that'the doffer-bars engage loosely against the drum by their own weight, and it is also desirable that they be thrown away from the drum upon the actuation of rock-shaft 81. To this end, the shaft 81 has secured thereto the collars 86 with transverse cut away portions 87. Each doifer bar is mounted .on a

supporting member 88 journaled on the shaft 81 and provided with extensions 89 which engage said cut away portions 87,

'meansfor actuating said movable and permit a slight lost motion between the parts.
